Application filed June 1, 191%. Serial No. 842,072,

To all whom it may concern:

Be it known that I, JAMES H. BAILEY, a citizen of the United States of America, and residing at New -York, in the county' of Kings and State of New York, have invented new and useful Improvements in Registers, of which the following is a specification.

This invention relates to registers and ventilators for heating and ventilating purtions in flow through the control of a single operating member.

These objects I have accomplished by employing a plurality of vanes which are adapted respectively to control flow through different portions of the register and by operating the vanes by a common operating member which serves, as it is actuated, to open the vanes sequentially or one vane after another. This enables one, by shifting the operating member only a limited extent, to open up flow through only a limited area of the register, or by shifting the said member further, to open up additional flow through the register. By having these vanes properly curved I avoid eddy currents which tend to choke the flue and outlet.

The accompanying drawings illustrate in concrete form a practical embodiment of the invention, it being understood that changes and modifications may be made therefrom without departing from the true spirit and scope of the invention.

Figure 1 is a vertical sectional view sh0wing an embodiment of the invention as'installed in an ordinary flue box, the vanes in this view being shown fully open. Fig. 2, is a perspective view of the register detached from the flue box. Fig. 3, is a vertical sectional View of'parts of the register, with the vanes closed. Fig. 4 is a'view of the side wall of the supporting frame, the opera ting sl de and the vanes all in detached relation. F igs. 5 and 6 are views illustrating the successlve opening of the vanes.

The flue box 7, is of typical provided with a wall outlet 8.

9 is the border frame which forms the fitting between the register and the wall.

construction,

The register illustrated has two main parts,

a grille 11 and a supporting flange or frame 12, at the back of the grille secured thereto for instance, by screws 13.

Mounted in the frame are the flow controlling vanes or fans, there being only two of them in this instance, an upper vane 15 and a lower vane 16. These vanes are pivoted at 17 and 18 to the side walls 19 of the frame. The vanes are preferably curved as shown so as to deflect and direct .the rising currents of air on an easy curvature on out through the face of the register, the

- lower vane controlling flow through the lower portion of the register and the upper vane controlling flow through the upper portion of the register. The lower vane is shown as somewhat smaller than the upper vane. The upper vane may be made to slightly overlap the lower vane in the closed position substantiallyas shown. Somewhat more uniform distribution of air may be obtained with three or more vanes but this increases the cost of manufacture. only a single vane hinged at the top is used, the air currents are such that air only flows out from the upper portion of the grille and in some cases in fact, air actually flows into the lower part of the grille.

The operating member for the vanes is here illustrated as a slide 21, slidingly supported at one side of the frame on the lugs 22. The connections whereby said slide is caused to open the vanes in succession, are in the shape of pin and slot connections be Where tween the slide and the respective vanes.

, from, this latter portion being shown as terminating in a reverse curve or inclination 33. A handle of some sort is usually provided for operating the slide, the handle here taking the form of a button 35 projecting forwardly through a slot 36 in the grille.

In the operation of the device as described, when the vanes are closed and it is desired to open up a limited flow through the register, the slide is pushed upward a slight disrelatively longitudinal idle portion 31 of tance, in the course of which the inclined working portion 27 of the lower slot acting as an inclined shoulder on the pin 25, swings the lower vane up into the open position shown in Fig. 5. During this movement of the slide, the operating pin 29 travels in the the upper slot and so communicates practically no movement to the upper vane. If it is desired now to open up more flow through the register, the slide is moved still farther up so that the pin 29 passes into the relatively inclined Working portion 32 of the slot, and acting as against an inclined shoulder, swings the upper vane open to a greater or less extent, dependent upon the additional movement actually imparted to the slide. The extent of this additional movement determines the amount of opening of the upper vane, which may be set anywhere from a slightly opened position such as indicated in Fig. 6 to the full open position indicated in Fig. 1 where it is opened substantially parallel to the lower vane. In the more fully opened positions of the upper vane when the weight of the vane is more eflective on the slide, the operating pin 29 passes into the reversely inclined or curved portion 33 of the upper slot which thereupon serves to lock the vane in its upraised position and to prevent the leverage exerted by the vane from forcing the slide down 'into closing position. During the additional movement of the slide necessary for the opening of the upper vane, the operating pin 25 on the lower vane rests in the relativelylongitudinal idle portion 28 of the lower slot whereby the lower vane is simply maintained in its already opened position. The vanes are closed by reversing the movement of the slide and in this closing movement the sequence of operation is reversed, the upper vane in this case being inmates closed before the lower. Where the register is used on a lower floor, a certain amount of air may be diverted from the flue by opening the lower vane only, leaving the remainder to flow on up to the next floor above. When the upper vane is fully open all the air is deflected through the register. By having a plurality of vanes it is possible to get a more uniform flow of air and to utilize the entire outlet area of the grille. Less force is required to operate the fans sequentially than simultaneously.

From the foregoing it will be realized that my invention provides a simple and very edective means for properly distributing the flow through the register and for controlling the volume of flow to just the extent desired.

What ll claim is v 1. A register provided with a discharge outlet, a plurality of vanes for controlling flow through said outlet, a single operating member and connections from said operating member for opening said vanes succes= sively one after the other.

2. In a register, a frame providing an outlet, a vane mounted in said frame and controlling the lower portion of the outlet, a vane mounted in the frame and control ling the upper portion of the outlet, and a. movable operating member arranged in its movement in one direction to open one vane to the full extent and by the further movement thereof to open the other vane to a controllable extent.

3. A vane construction for registers comprising, a supporting frame, upper and lower vanes pivoted therein, an operating slide mounted in the frame, connections between the slide and the lower vane for swinging said vane to open position during the first part of the movement of the slide in one direction and connections between the slide and upper vane for swinging the upper vane open in the continued movement of the slide in the same direction.

4. In a register, a plurality of pivotally supported vanes, an operating slide for said vanes, connections between the slide and one of the vanes embodying a pin on the vane and a receiving slot on the slide having an inclined portion engaging the pin in the first part of the movement of the slide to lift the vane to open position and a straight longitudinal portion to hold the vane open in the further movement of the slide and connections between the slide and a second vane embodying a pin on the slide and a receiving slot on the vane having a relatively straight longitudinal portion receiving the pin during the first part of the movement of the slide and a relatively inclined portion engaging with the pin for lifting said second vane during the further movement of the slide.

5. In a register, a pivotally supported portion and avrelatively inclined working vane, an operating slide and connections beportion terminating in a reversely inclined tween said slide and the vane embodying locking portion. an operating pin on one of said members JAMES H. BAILEY.
